It was pissing it down here today. Ds1 likes to go out and get soaked, deliberately get himself wet and play in the rain. He has wellies etc but chooses to go out in his trainers. This annoys me and when he does it I have told him he must put paper in his shoes and put them in the airing cupboard, otherwise they are still wet in the morning and he can't wear them . He got athlete's foot before from wearing wet shoes the next day 
He doesn't have spare shoes and doesn't like wearing his wellies so he won't be happy in the morning when he finds his shoes are still soaking. He's left them in the hall (also his raincoat is there lying on the floor soaking wet, so if it's raining tomorrow that will be uncomfortable to wear also).
He's 7 and he's just gone to bed. Should I pick them up or leave them?
